Coalition for Equitable Water Flow (

Our members have told us that the fluctuating water levels are a very important issue to them. These fluctuations affect boating, docks, fish spawning and loon nesting. For example by letting the water out too early all the Lake trout eggs on Mountain Lake were killed a few years ago.

Given the significance of this issue MBC is an active member and financial supporter of the Coalition for Equitable Water Flow, a volunteer organization that represents the interests of people like us on the reservoir and flow through lakes to the Trent Water System.

A NEW SERVICE FROM Parks Canada / TSW (Aug 30 – 2014) 

WIth Thanks to our good Friends at the Kushog Lake Association!

The TSW will now be posting regular water level forecasts on their website. Click here – TSW Forecast – to see the latest.

It is important to note that a significant “drawdown” during a given period for lakes “upstream” of Maple and Beech Lakes ( in particular Redstone and Eagle Lakes ) could cause a temporary rise in water levels for MBC’ers.

Note, also, that rain or operational issues may affect the accuracy of these forecasts.  Make sure that boats and docks are secured appropriately if you will be away from the lake during a period of significant drawdown!


As you can see, 2014 has been a really wet year (in case you hadn’t noticed all that rain) so far and water levels have remained above “normal” for much of the summer. The measuring station – Don Wetmore’s dock – is stable and gives an excellent picture of where levels are on both Maple and Beech Lakes when compared from year to year. These measurements fairly easily compared to data provided, from time to time, by the TSW and eventually we will be able to use the combined data to give some advanced notification of extreme highs and lows based on flow planning from the TSW.

Check in now and then to see what’s up (or down)!
